The Battle of Kolín on 18 June 1757 saw 54,000 Austrians under Count von Daun defeat 34,000 Prussians under Frederick the Great during the Third Silesian War (Seven Years' War). Prussian attempts to turn the Austrian right flank turned into piecemeal frontal attacks and were defeated in five and a half hours of combat. The Prussians lost 13,700 men, the Austrians 8,100. Frederick gave up the siege of Prague as well as his planned march on Vienna and retreated to Saxony. Daun did not pursue.
